These Traditional Garden Planters are manufactured from the latest environmentally friendly material Ôfibre clayÕ, a composite of clay, fibreglass and magnesia which is much stronger conventional terracotta/clay and much cheaper than polyresin or fibreglass. This construction offers superior strength and stability in construction, resulting in a fantastically durable, lightweight product. It also produces a much more natural looking, durable plinth, ideal for outdoor use.
